SPECIFICATION forming part of Letters Patent N 0. 540,052, dated May 28, 1895.

Application filed November 17, 1394:. $erial No. 529,128. (No model.)

To aZZ whom it may concern.-

Be it known that I, BJoEN E. HAUGEN, a citizen of the United States, and a resident of Hillsborough, in the county of Traill and State of North Dakota, have invented certain new and useful Improvements in Grain Elevators and WVeighers for Threshing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in grain elevators and weighers for thrashing machines, of that class or character in which the grain as it comes from the separator is elevated and deposited in the weighers and from thence dumped into a chute which conveys it to bags, wagons or other receptacles.

The object of the invention is to provide an improved construction of the same, whereby the elevator when not in use may be tilted over to the center of the thrashing machine so as to distribute the weight more evenly and uniformly; and also to provide an improved weighing mechanism which will automatically dump the grain received from the elevator when a predetermined amount has been fed to the weighing mechanism.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings,Figure 1 is a side view of a thrashing-machine, showing my improvements applied thereto. Fig. 2 is a longitudinal sectional view taken through the center of the elevator. Fig. 3 is a transverse section of the same. Fig. 4 is a detail side elevation of the weighing mechanism. Fig. 5 is an end view of the elevator. Fig. 6 is a detail perspective view of the weighingcylinder.

In the said drawings the reference numeral 1 designates a thrashing machine of any ordinary or suitable construction, provided with the usual separator 2, for separating the grain from the chaif and dirt.

The numeral 3 designates the elevator or conveyor, made in two sections, an upper and a lower one, each consisting of two rectangular tubes t and 5. The upper ends of the tubes of the lower section are connected together by a transverse plate 6, which is connected with a beam 7, secured to the thrasher. The outer end of this beam is provided with a vertical standard or upright S, which supports the outer end of an inclined beam 9, the inner end of which is secured to beam 7. Secured to the meeting ends of said beam and standard is a bracket 10, in which is journaled a pulley 12, around which passes a rope 13. This rope is secured to a rod is secured to the tubes 4, and passes around a pulley 15 connected with beam 7, and its ends are secured to and wound in opposite directions upon a Windlass 16, secured to the lower section of the elevator or conveyer. lass is provided with a crank 17 and a ratchet wheel 18, with which engages a pawl 19.

The upper section of the elevator or conveyer is hinged or pivoted at 20, to the lower section, and the lower ends of tubes 4 overlap the upper ends of tubes 5. At its outer side the upper section is provided with catches 21 with which engage spring hooks 23 secured to the lower sectionavhich hooks are connected together by means of rope 2a. The object of these hooks and catches is to hold the uppersection in a vertical position when in use.

The lower section of the elevator is provided with a curved base 25, which connects the lower ends of tubes 5 together, and is provided at one side with a hopper 26 with which communicates a spout 27 leading to the separator 2. .Iournaled in this base is a shaft 28, provided with two flanged pulleys 29 over which pass endless belts or bands 30, provided with a series of buckets 31. These belts or bands also pass overa flanged pulley 32 secured to a shaftSl journaled in the sides of a cap 35 which connects the upperendsot tubes eltogether. This shaft is provided with a pulley 36, which is connected by means of the belt 37 with a pulley 38 of the shaft of the separator.

The cap 35, at one side or end is provided with an extension 39, forming a chute which receives the grain elevated by the buckets 31, and delivers it to the weighing mechanism. This weighing mechanism consists of a cylinder 40, divided centrally by means of avertical partition 41 into two weighing chambers,

This windeach provided with an opening 42 at the top to alternately receive the grain fed from the elevator, and an opening 43 at'the lower end for the delivery of the grain after having been weighed. The lower ends of these chambers are closed by means of gravity-gates 45,

hinged to the said cylinder, which gates are actuated to alternately open and close said openings, as hereinafter described. The ends of the cylinder 40 are provided with studs 46, which are journaled in brackets 47 having upwardly extending arms 48, secured to the ends of a yoke or bail 49, which is pivoted at 50 to the upper elevator section; This yoke is provided with a downwardly extending rod 51 passing through a guide-plate 52, secured to said section and provided with a number of removable weights 53. The inclined arms ,54, of the brackets 47 are provided with transverse rollers 55 with which the gravity-gates 45 are adapted to engage when the cylinder is oscillated, so as to close the openingsin the bottom thereof. These arms are also provided with an open bottom-pan 56 by which the grain delivered from the weighing chamber is guided into a spout or chute 57 below, which conveys the grain away from the machine.

One of the ends or heads 58, of the cylinder 40, is provided with an upwardly extending lug 59, which is adapted to engage with a roller 60, journaled on a stud 61, secured to the extension 39. Secured to the lower ends of the said cylinder are lugs 62, through which pass rods 63, to which the gravity gates are hinged or pivoted. These lugs project outwardly a short distance beyond the periphery of the cylinder and also serve as stops for the same by engaging with transverse rods 64 secured to the bracket 47.

The operation is as follows: The grain as it comes from the separator is conducted to the lower part of the elevator, from which it is conducted by the buckets and endless band to the upper part thereof, from whence it falls into the chute 39. From this chute the grain falls into one of the weighing chambers, the gravity-gate of which, engaging with the roller 55, closes the opening in the lower end thereof. When a sufficient quantity of grain has been fed to the weighing chamber to overcome the weight connected with the bail or yoke, the latter will tilt, disengaging the lug 59 from the roller 60, and allowing the cylinder to turn or rotate by reason of the weight of the grain contained therein, lugs 62 on the periphery of the cylinder engaging with one of gate opens and the grain falls out of the said chamber into the chute or spout below. As the yoke or bail is returned to normal position by its weight, the cylinder will be elevated and the opposite side of the lug 59 will engage with the roller so that the other weighing chamber will coincide or register with the chute 57 and its pivoted gate closed by its roller 55. The grain will now be delivered to this last-mentioned chamber until the weight of the yoke or bail is overcome, when the cylinder will again descend and rotate in the opposite direction to dump the load in the manner previously described. It will thus be seen that the weighing chambers will be alternately filled and discharged by the oscillation of the cylinder and the operation will be contin nous, so long as snflicient grain is fed thereto to overcome the weight of the yoke or bail.

When the elevator is not in use, the windlass, see Fig. 3, is rotated to the left, causing the rope 13, on the left to be wound upon and the end at the right to be unwound from the Windlass. This will cause the rope at the left of shaft 14 to be unwound therefrom andthe slack at the right from the Windlass to be wound thereupon, causing the upper section of the elevator to be tilted over on the thrasher. A reverse movement of the windlass will return the elevator to normal position.

Having thus fully described my invention, what I claim is' 1. In a grain elevating mechanism for thrashing machines, the combination with the elevator made in two sections, each section consisting of two parallel rectangular tubes, the lower ones being connected together by a base and the upper ones by a cap, and the meeting edges overlapping each other. and hinged together, the shafts journaled in said base and cap, respectively, the wheels secured thereto, and the endless band or belt passing around said wheels and provided with buckets, of the transverse-shaft journaled to said upper section below the cap, the beam and standard for supporting the lower section, the Windlass, the shafts provided with pulleys, and the rope wound upon said transverse shaft journaled to-the upper section and upon the windlass,in opposite directions and secured to the Windlass, substantially as described.
